TOOL.

SPECIFICATION forming part of Letters Patent No. 706,184, dated August5, 1902.

Application filed May 1, 1902. $erial1lo. 105,485. (No model.)

To all whom, it Wuty concern:

Be it known that I, JERRY HENRY KOCH, a citizen of the United States,residing at Alpha, in the county of Doddridge and State of WestVirginia, have invented certain new and useful Improvements in Tools;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The invention relates to tools, and more particularly to an improvedform of wedge by means of which a tool may be more securely connected toits handle and the handle braced or strengthened at that portionhitherto subjected to the greatest strain and where breakage most oftenoccurs.

The object of the invention is to provide a wedge of this characterwhich shall be simple of construction, durable in use,comparativelyinexpensive of production, and easily applied to tool-handles foreffecting a secure connection of the tool to the handle.

With this and other objects in view the invention consists of certainnovel features of construction, combination, and arrangement of parts,which will be hereinafter more fully described, and particularly pointedout in the appended claims.

Figure 1 is a side elevation showing in dotted lines the application ofmy improved wedge to a hatchet and its handle. Fig. 2 is a detail sideelevation of the wedge. Fig. 3 is a cross-sectional view on line was,and Fig. at is a similar View on line y y.

Referring to the drawings, A denotes a hatchet,and B the handle,insertedinto the eye of the hatchet in the usual manner, but before which it isformed with a bore to receive a wedge.

C denotes the wedge, which consists of a piece of metal formed oflongitudinal ribs 1 and flanges 2, projecting laterally therefrom atright angles to the line of projection of the ribs and formed withcorrugations which are arranged at an acute angle to the length of theflanges. The wedge is formed with a driving-head 3, and from thisdriving-head these side flanges taper to a point at, where they suddenlymerge into the ribs, as shown, thusproducing a penetrating-point. Afterthe handle has been secured to the tool by having its end insertedthrough the eye thereof the wedge is inserted into the bore previouslymade in the handle, and by subjecting it to several blows it is drivendownwardly into the handle in the position shown in dotted lines in Fig.1 until the head becomes flush with the outer end of the handle. Thereis no liability of the wedge becoming accidentally disengaged from thehandle, for the reason that the corrugations, while permitting of thefree and easy insertion of the wedge into the handle-bore, will preventthe withdrawal therefrom, owing to the direction of their projection. Ofcourse it is understood that the bore in the handle will not incrosssection equal or be of the same shape as the wedge incross-section, thereby causing said wedge to firmly bind itself in thebore when driven home. It will be noticed that the wedge extends aconsiderable distance of the length of the handle and materiallystrengthens that portion of the handle adjacent to the eye of the tool,at which point the handle most often breaks.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, mode of operation, andadvantages of the invention will be readily understood without requiringan extended explanation.

Various changes in the form, proportion, and details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim, and desire to secureby Letters Patout, is-

1. A wedge for the purpose described, consisting of a body portionformed on its opposite sides with longitudinal ribs and upon itsopposite edges with 1ongitudinally-corrugated flanges, said flangestapering from one end of the body portion to the other and merging intothe ribs, substantially as set forth.

2. A wedge for the purpose described, cousisting of a body portionformed on its opposite sides with longitudinal ribs and upon itsopposite edges with longitudinally-oorrugated flanges, said flangestapering from one end of the body portion to the other and merging intothe ribs,said body portion being provided at its opposite end with adriving-head, sub

ribs, said body portion being provided at its opposite end with adriving-head, substantially as set forth.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JERRY HENRY KOCH.
